Given:

Distance travelled and direction: 125 meters to the north(+125), 75 meters to the south(-75)

Find the displacement.

Basing on the Cartesian Coordinate Plane, going to the north means positive, and going to the south means negative. In order to find the displacement, we combine the 2 values.

=125 meters - 75 meters

= 50 meters

The total displacement is 50 meters to the north.
